Caprine encephalomyelomalacia.

Area of Science:

• Veterinary Neurology
• Pathology
• Ruminant Medicine

Background:

• Encephalomyelomalacia (EPM) is a neurological disease affecting young animals.
• Dairy goats are susceptible to various neurological conditions.
• Understanding EPM's pathology is crucial for diagnosis and treatment.

Purpose of the Study:

• To describe the clinical and pathological findings of encephalomyelomalacia in dairy goats.
• To identify the specific locations and characteristics of lesions in affected goats.
• To contribute to the understanding of EPM in young ruminants.

Main Methods:

• Case study of six dairy goats aged 3.5 to 4 months.
• Clinical observation of neurological signs, including onset and progression.
• Necropsy and histopathological examination of the spinal cord and brain stem.

Main Results:

• Abrupt onset of neurological signs, progressing from ataxia to paralysis.
• Spinal cord and brain stem lesions were consistently observed.
• Lesions were bilaterally symmetrical, necrotic, and primarily affected the ventral and intermediate gray matter of the spinal cord and specific brain stem nuclei.
• Spinal cord enlargements showed the most severe pathology.

Conclusions:

• Encephalomyelomalacia presents with rapid neurological deterioration in young dairy goats.
• The characteristic lesion distribution involves the ventral and intermediate gray matter of the spinal cord and specific brain stem nuclei.
• The spinal cord enlargements are particularly vulnerable in this condition.
